On December 2, 2022, police in Nashua responded to a shooting at a residence on Amherst Street and found 57-year-old Joseph Bisson with gunshot wounds. He was pronounced dead at the scene. An autopsy the next day showed Bisson had been shot in both the abdomen and the head, and the manner of death was ruled a homicide.

The Attorney General’s Office and the Nashua Police Department opened a joint investigation. Authorities say they believe they have identified all involved parties and that there is no ongoing threat to the community, but no arrests have been announced. The shooting has left Nashua searching for answers.

Anyone with information about Bisson’s activities in the hours before the shooting is asked to contact the Nashua Police Department.
